Which of the following is something that probably would NOT be studied in a lab? A. what molecules are found in tea

B. how birds migrate thousands of miles

C. how hydrogen gas behaves as it is cooled

D. what skin cells look like under a microscope

The answer is option B

Explanation:

The answer is option B because the number of molecules found in tea can be done experimentally in the labs. Particularly in the chemistry labs, it will be shown. Hydrogen gas behavior is shown in chemistry practical labs. In the lab, they will teach how the hydrogen gas will behave when it is cooled. In the physics lab, they will teach and show the microscope. They will show things inside the microscope. They will practically show the skin cells in the microscope. But the migration of birds in thousand miles will not be shown in labs. So the answer is option B
